The original author of the VRRPD code is the most excellent Jerome Etienne. 
  I've contacted him to see what he knows about this...

The code isn't really that hard.  The current code knows how to format the 
packets.  It's basically a matter of convincing the OS to let you send out 
ARP packets instead of UDP or TCP...

The current code can do some things we never do, like lie about our MAC 
address.  We don't need that.

Time to get out your Stevens books...
